Witchita is leaving for the Salem School of Witchcraft, a special school that will have her away for the entire summer. The Mighty, Mighty Monsters are sad to see her go, but Witchita is excited to learn all new sorts of witchery. A few days after she leaves, they receive a letter from Wichita saying that she's monstrously miserable! The gang immediately hits the road to save their sorrowful friend from summer school.
